A new electrode structure of Li-ION batteries by QuantumSphere could lead to higher capacities able to keep your gadgets going up to five times longer than usual. The original anode capacity is only ten percent of the weight of a battery. By increasing the percentage of the anode weight to fifty, its surface area also increases dramatically. This larger area that's enriched with nano lithium particles is responsible for the increase in battery life.

The most obvious use for this technology in the future would be for mobile computing, of course. For laptops, the vision is to set a new standard of 12 hours of use per single charge, while for cell phones, the charge is expected to last for four days on average. It could also be employed on batteries meant for hybrid vehicles. QuantumSphere already filed a patent for its new technology and has raised $20 million for the project. Earlier this month, HP claims to have developed a battery that lasts up to 24 hours while even earlier on, Dell (pdf) claimed 19 hours battery life.
